(2 Points)
Enter your answer

Answer 1

12 square units

Explanation:

The area of a given figure is the measure of space occupied by the figure on a 2 dimensional plane.

Area of a triangle =
`(1)/(2)` x base x height

From the given grid, the following can be observed for triangle STU.

base SU = 6 units

height = 4 units

Thus,

area of triangle STU =
`(1)/(2)` x base x height

=
`(1)/(2)` x 6 x 4

= 3 x 4

area of triangle STU = 12 square units

The required area of triangle STU is 12 square units.
